NASA and Phys.org describe new imagery and observations of ice breaking from the Tyndall Glacier in southern Patagonia. They report that ice splinters off the glacier and drifts across a proglacial lake that is enlarging. The articles place the event in the broader context of the Southern Patagonian Icefield, described as the largest ice expanse in the Southern Hemisphere outside Antarctica. According to the reports, thick ice stretches hundreds of kilometers along the Andes and feeds many outlet glaciers. These glaciers flow down from higher elevations and can end either in the sea or in proglacial lakes. As outlet glaciers advance and retreat, calving and related ice break-up can supply ice to these lakes, where drifting bergs spread across the water body. Both sources emphasize the movement of bergs across the lake following calving, and they frame the phenomenon as part of how Patagonia’s glacier system transfers ice from the icefield to surrounding waters.
Icebergs from southern Patagonia’s Tyndall Glacier drift across a growing proglacial lake

- Ice splinters calve off the Tyndall Glacier in southern Patagonia.
- The detached ice drifts across a nearby proglacial (glacial) lake.
- The proglacial lake is described as growing.
- The Southern Patagonian Icefield is identified as the largest ice expanse in the Southern Hemisphere outside Antarctica.
- Outlet glaciers flowing from the Andes supply ice that can terminate in the sea or in proglacial lakes.
The Southern Patagonian Icefield is the largest expanse of ice in the Southern Hemisphere outside Antarctica. The mass of glacial ice extends hundreds of kilometers along the spine of the Andes, feeding dozens of dynamic outlet glaciers that grind their way down from higher elevations. Many of these rivers of ice terminate in the sea or in proglacial lakes.
